Abstract

A communication method and apparatus. The communication method includes: A terminal device transmits first capability information to a first network device, where the first capability information indicates that the terminal device supports sending a sounding reference signal (SRS) by using a maximum of a first bandwidth size of bandwidth; the terminal device transmits second capability information to a second network device, where the second capability information indicates that the terminal device supports sending data or control information by using a maximum of a second bandwidth size of bandwidth; the terminal device obtains first configuration information indicating that a size of bandwidth configured for the SRS is not greater than the first bandwidth size; and the terminal device obtains second configuration information indicating that a size of bandwidth configured for the data or control information is not greater than the second bandwidth size.

Claims (52)

1 . A communication method performed by a terminal device or a chip in the terminal device, the method comprising:

transmitting first capability information indicating a first bandwidth size which is a maximum bandwidth supported by the terminal device for sending a sounding reference signal (SRS);

transmitting second capability information indicating a second bandwidth size which is a maximum bandwidth supported by the terminal device for sending data or control information, wherein the first bandwidth size is greater than the second bandwidth size;

obtaining first configuration information, wherein a size of bandwidth for the SRS indicated by the first configuration information is not greater than the first bandwidth size; and

obtaining second configuration information, wherein a size of bandwidth for the data or control information indicated by the second configuration information is not greater than the second bandwidth size.

2 . The method according to claim 1 , wherein the first bandwidth size belongs to a first bandwidth size set, and at least one bandwidth size in the first bandwidth size set is greater than the second bandwidth size.

3 . The method according to claim 1 , wherein the method further comprises:

sending third capability information indicating one or both of:

whether the terminal device supports sending and/or receiving the SRS in a carrier aggregation manner; or

the terminal device supports sending and/or receiving the SRS using a maximum of M carriers, wherein M is a positive integer.

4 . The method according to claim 1 , wherein the method further comprises:

sending fourth capability information indicating one of:

the terminal device does not support sending and/or receiving the data or control information in a carrier aggregation manner; or

the terminal device supports sending and/or receiving the data or control information using a maximum of N carriers, wherein N is a positive integer.

5 . The method according to claim 4 , wherein N is less than M; or N is not greater than M.

6 . The method according to claim 1 , wherein the first capability information is transmitted to a base station or a location management function (LMF), and the second capability information is transmitted to a base station.

7 . A non-transitory computer-readable media storing instructions that configure at least one processor, upon execution of the instructions to perform:

transmitting first capability information indicating a first bandwidth size which is a maximum bandwidth supported by a terminal device for sending a sounding reference signal (SRS);

transmitting second capability information indicating a second bandwidth size which is a maximum bandwidth supported by the terminal device for sending data or control information, wherein the first bandwidth size is greater than the second bandwidth size;

obtaining first configuration information, wherein a size of bandwidth for the SRS indicated by the first configuration information is not greater than the first bandwidth size; and

obtaining second configuration information wherein a size of bandwidth for the data or control information indicated by the second configuration information is not greater than the second bandwidth size.

8 . The computer-readable media according to claim 7 , wherein the first bandwidth size belongs to a first bandwidth size set, and at least one bandwidth size in the first bandwidth size set is greater than the second bandwidth size.

9 . The computer-readable media according to claim 7 , wherein the at least one processor further executes the instructions to perform the step of:

sending third capability information indicating one or both of:

whether the terminal device supports sending and/or receiving the SRS in a carrier aggregation manner; or

the terminal device supports sending and/or receiving the SRS using a maximum of M carriers, wherein M is a positive integer.

10 . The computer-readable media according to claim 7 , wherein the at least one processor further executes the instructions to perform the step of:

sending fourth capability information indicating one of:

the terminal device supports sending and/or receiving the data or control information using a maximum of N carriers, wherein N is a positive integer.

11 . The computer-readable media according to claim 10 , wherein N is less than M; or

N is not greater than M.

12 . The computer-readable storage medium according to claim 7 , wherein the first capability information is transmitted to a base station or a location management function (LMF), the second capability information is transmitted to a base station.

13 . An apparatus, comprising:

a memory storing instructions; and

at least one processor in communication with the memory, the at least one processor is configured, upon execution of the instructions, to perform the following steps:

transmitting first capability information indicating a first bandwidth size which is a maximum bandwidth supported by a terminal device for sending a sounding reference signal (SRS);

transmitting second capability information indicating a second bandwidth size which is a maximum bandwidth supported by the terminal device for sending data or control information, wherein the first bandwidth size is greater than the second bandwidth size;

obtaining first configuration information, wherein a size of bandwidth for the SRS indicated by the first configuration information is not greater than the first bandwidth size; and
